Abstract The ex-situ catalytic pyrolysis of sugarcane bagasse with various HZSM-5 (23, 50, and 80) catalysts was studied in a tandem micro reactor-GC/MS at 400 °C, 450 °C, 500 °C and 550 °C with a catalyst to biomass (C/B) ratios ranging from 2 to 23. The yields of benzene, toluene and xylenes (BTX) were significantly affected by pyrolysis temperature and C/B ratio. The highest BTX yield of 22% was obtained for the HZSM-5 (23) catalyst at C/B ratio of 12.5 and a temperature of 475 °C. Finally, an experimental design was performed to determine the optimal process conditions for BTX yields.

甘蔗渣异位催化快速热解生产苯、甲苯和二甲苯（BTX）

摘要 在串联微型反应器-GC/MS 中，在 400 °C、450 °C、500 °C 和 550 °C 下研究了用各种 HZSM-5（23、50 和 80）催化剂异位催化热解甘蔗渣。 C 与生物质 (C/B) 比范围为 2 到 23 的催化剂。苯、甲苯和二甲苯 (BTX) 的产率受热解温度和 C/B 比的显着影响。在 C/B 比为 12.5 和温度为 475 °C 时，HZSM-5 (23) 催化剂获得了 22% 的最高 BTX 产率。最后，进行了实验设计以确定 BTX 产量的最佳工艺条件。
